BELT ATTACH MENT.

SPEGIFICATION forming part of Letters Patent No. 253,548, dated February 14, 1882.

: Application filed December 31,1881. (No model.)

To all whom it may concern:

Be it known that I, BENJAMIN MERRITT, a citizen of the United States, residing at New tn, in the county of Middlesex and State ot' Massachusetts, have invented a new and usefulImprovementinBelt Attachments, ofwhich the f'ollowing is a specification.

My invention relates to devices to be used in connection with a belt of a light-running machine, and has for its objects to admitof the tipping up of the machine for the purpose of examination, adjustment, or oiling, without removing the belt; also to provide a brake device to operate in connection with the belt for the purpose of stopping the machine quickly. I attain these objects by the mechanism illustrated in the accompanying drawings, in which-` Figure l is aview in side elevation, showing the bed, driving-shaft,'and pulley of a sewingmachine, and beneath it the apparatus for transmitting motion. Fig. 2 is a front elevation, showing the transmitting apparatus.

Let A A A2 represent a part of the bed, the driving-shaft, and pulley ot' the machine to he operated; this machine being hinged to the bench or table at A3, Fig. 1.

C is a counter-pulley hung upon a swinging counter-shaft, C', which also has upon it the friction-pulley E, Fig. 1. This counter-shaft C' is attached to the swinging hangers Dl D', (see Figs. 1 and 2,) the upper end ot' these hangers being rigidly attached to the cross-bar D3, Fig. 2, said crosshar D3 oscillating freely in the fixed hanger D. (See Figs. l and 2.)

L is afoot-lever rigidly attached to the crossbar D3, so that any movement ofthe foot-lever L causes a corresponding movement of the hangers D D', the heltpulley C, and the friction-pulley E.

H is a fixed counter-shaft, having upon it a driving-pulley, H', and a friction-pulley, K,

-ward the pulley C, but is connected indirectly to the pulley C by the spring S, which connects directly with the swinging hangerD, the action of the spring S being to draw the swinging counter-shaft C away from the friction-wheel K. The arm D2 has attached toits lower end a projection, D4, which overlies the bel't B, as shown in Fig. 2. This part D4 acts as a friction-stop for the belt B when the frictiolrpulley E is swung away from contact with the friction-pulley K, as shown inFig.1; but when the friction-pulley E is pushed by the lever L into contact with the pulley K, then the belt B moves away from the part D* and is nolonger prevented from operating.

I claim as my inventionl. The combination of the pulley A2 and belt B with the pulley C, swinging counter-shaft C', friction-pulley E, jointed housing D D D, and foot-lever L, all operating together in conf junction with the friction-pulley K, substantially as described, and for the purpose set forth.

2. The combina-tion of the brake D2 D4 with the belt B, pulleyO, counter-shaft C', and jointed housingD DD,all operating together substantially as described, and for the pur- F. L. FULLER., FRANK G. PARKER.
